How are your guys' flow rates with sand/fish/inverts?

I am setting up a 45 gallon cube (24x24x18high) and bought two tunze 6000's with 7095 multicontroller.. Planning on throttling them both back to minimum 30% and possibly have them alternate between 30-40% for some flow variation..

I'm planning on keeping mostly SPS with maybe a couple of flow tolerant soft corals and zoo's. Also clam/anemone..

This will work out to be somewhere in between 30-40x flowrate, altho I have the option to go all the way up to 92x if I wanted to turn the powerheads up all the way..

How are your fish in your tanks? Are we limited to our fish selection based on our high flow rates? I posted something like this in the main reef discussion forum and basically got a "woah that's way too much flow! your fishes scales will fly right off!" or "you cant use anything but barebottom or crushed coral"..

I was planning on having 4-5 smaller fish.. I also was planning on having a shallow sand bed of oolitic.. But again I got the "if you use oolitic sand it will be on the floor!" responses..

So given my tank dimensions and turnover rate possibilities, what do you guys think? Also how would you place/angle the tunze's ? I was thinking both at the back corners pointing towards the front-middle so the flow collides..

rockwork is planned to be in the middle of the tank, no rock wil touch the sides.

thanks!

Just going to bump this once, then I'll let it die.

I just use 2 RIO 600s with HydroFl0 adapters. Provides plenty of current for me. I can't imagine putting any more force on my xenias. My tank is 24" wide, but it lacks your depth and height.
